REINFORCED CYLINDRICAL CASK.

SPECIFICATION formingpart of Letters I'atent No. 732,995, dated July 7, 1903. Application filed February 9, 1903. SB I'lItINOr 142,567- (No model.)

To wZZ whom it may concern.-

Be it known that I, WILLIAM G. AVER a citizen of the United States, residing at Painesville, in the county of Lake and State of Ohio, have invented certain new, and use 'ful Improvements in Reinforced Cylindrical Gasks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to sheet-metal casks, such as are more especially designed for receiving and containing productsof manufacture either in a heated or cold condition and struction of the cask as a whole embodying certain characteristics, which will be hereinafter fully set; forth, and especially pointed out in the claim.

In the drawings, Figure I is a vertical sectional view taken through a cask embodying my invention. Fig. II illustrates a cask bent into approximate shape and as it appears before the meeting edges are fastened together. Fig. III illustrates the body of a cask complete after it has been riveted or after the meeting edges have been secured.

Inasmuch as my invention relates to the construction of the body of the cask, I have not illustrated the bottom or top, if any were I used, in connection with it, leaving this as a matter of convenience'or option. In forming a cask, according to my invention I takea blank of metal of such shape that in one cross-section it will be equivalent in length to the circumference of the cask at every part. The other cross section of the 3 blank will equal the height'of the cask plus the amount of material required for the fold or reinforcements hereinafter set forth. The blank isfirst folded, as illustrated at A, Fig. I,by bending the metal approximately at right angles, thence approximately parallel with the body,"thence again at right angles and in an opposite parallel direction, and repeating this fold in the inverse order, thus forming a reinforcement or hook, as at A. The fold is so formed that it is of uniform width and thickness and in such a manner that its edges (1 a will meet. There may be one, two, or more of these folds or reinforcements or hooks formed, as illustrated. For the top or bottom, or for either, the folds B C are made to extend outward, thence parallel, inward, and again parallel with the body'of the metal, thus giving the same uniformity and thickness to the upper and lower edge, or either of them, as the reinforcements or books A, and providing three thicknesses of metal at all these parts. After these folds have been made while the sheet is in a Hat condition the sheet is passed through a press, preferably a rollerpress, and the reinforcements are pressed tightly and uniformly to shape.

In putting the cask together it isdesirable that the outer surface should be asfar as possible uniform or even at its meeting edges, and to attain this I have found it desirable ;to cut away a portion of the reinforcement,

as at b bf 19 thus allowing the edges to meet practically flush. This cutting away of the reinforcements A, B, and" C may be done in the blank before the folds are made, which is preferable, or they may be subsequently cut away if found desirable or necessary.

. In riveting the meeting edges of the cask I .find that it is desirable that rivets be placed in close juxtaposition, as at c o, to the hoops A. The placing of the rivets in close juxtaposition to the hoops keeps the joint at this part more firm and prevents distortionof the cask, which would result in an outward projection of the hoop at this point, making an uneven and undesirable construction. This,

ries of corrugations in the form of circles embracing the container; but this I do not claim, as the same is a much inferior article and would not sustain the rough usage to which casks or containers of my type are subjected.

I am also aware that attempts/have been made to form containers into shape by folding them or folding the metal upon itself in a vertical direction; but a container of this type would not in any manner meet the requirements of a cask formed according to my invention, as the strength or reinforcement would not be in the direction required and the forming of the upper edge of the container smooth is impractical to attain.

hoga and State of Ohio, this 30th day of January, 1903.
